Currently, the abnormal morphology of LAM is assessed with an unaided subjective diagnosis. But T2 mapping can quantitatively evaluate the injury muscle and indicate the injured degree and region of the LAM. In this study, we investigate whether the quantitative MR T2-mapping can evaluate birth-related levator ani muscle injury. The results showed that T2-mapping can quantitatively assess birth-related levator ani muscle injury and T2-mapping color-coded images show the range and degree of LAM injury visually. Moreover, it is helpful for detecting micro lesions which is difficult for just using PDWI images.
